APELIN promotes hematopoiesis from human embryonic stem cells.

Transcriptional profiling of differentiating human embryonic stem cells (hESCs) revealed that MIXL1-positive mesodermal precursors were enriched for transcripts encoding the G-protein-coupled APELIN receptor (APLNR). APLNR-positive cells, identified by binding of the fluoresceinated peptide ligand, APELIN (APLN), or an anti-APLNR mAb, were found in both posterior mesoderm and anterior mesendoderm populations and were enriched in hemangioblast colony-forming cells (Bl-CFC). The addition of APLN peptide to the media enhanced the growth of embryoid bodies (EBs), increased the expression of hematoendothelial genes in differentiating hESCs, and increased the frequency of Bl-CFCs by up to 10-fold. Furthermore, APLN peptide also synergized with VEGF to promote the growth of hESC-derived endothelial cells. These studies identified APLN as a novel growth factor for hESC-derived hematopoietic and endothelial cells.
